Specification of Letters Patent.

Patented July 15, 1919.

Application filed November 8, 1918. Serial No. 261,669.

To all whom it may concern:

Be it known that I, DAVID HOUSTON Mo- KELLAR, of 34 Brandon street, Motherwell, Scotland, have invented certain new and useful Improvements in and Connected. with Finger-Rings, of which the following is a specification.

My invention relates to improvements in and connected with finger rings of the kind where two dilierent emblems or designs can be exposed at separate times, by the movement of the center or signet part and has for its object to provide one of a very simple and eflicient nature.

In carrying out the invention, I provide a suitable slide working in a guide formed in the upper part of the ring. Carried on this slide is the center or signet part of the ring on each side or face of which the emblems or designs are engraved, carved or otherwise placed.

When it is desired to reverse the emblem, the hinged end of the center or signet part is depressed, when the other end rises. It is then gently pulled along with the slide to the opposite side of the ring and then turned down when the other emblem or design is exposed.

As a slightly modified form of carrying out my invention, the guide is in the form of a slot or cut-out in the center portion of the upper part of the ring, in which the slide, which is in the form of a small pin suitably hinged or pivoted to the center or signet part of the ring, works. At each end of the slot or cut-out there is a small piece which engages a small cut-out at each end of the signet part, and so looks when in position, or a small pin on the side of the center position of the ring engaging a small hole in the signet part effects the same object. In this case, when it is desired to reverse the emblem or design, the lock is released and. the center or signet part is raised up. It is then pulled gently along the guide till it reaches the end thereof, when it is pressed down and becomes locked, the other emblem or design being then exposed.

In order that my invention may be properly understood and readily carried into effect, I have hereunto appended one sheet of drawings, of which Figure 1 is a plan made in accordance my invention.

Fig. 2 is part a side elevation and part view of a finger ring with and embodying vertical section of the same, both of which figures are drawn to an enlarged scale.

Fig. 3 is a further vertical section of part of the ring drawn to a further enlarged scale.

Fig. 4 is a View corresponding to Fig. 1 of a modification of the improvements.

Fig. 5 is a part elevation and part vertical section of the same and corresponding to Fig. 2 drawn to an enlarged scale, and

Fig. 6 is a further vertical section of part of the same ring drawn to a further enlarged scale, and corresponding to Fig. 3, all hereafter more fully referred to and described.

Referring to Figs. 1 to 3 inclusive, the signet portion of the ring is provided with a rectangular shaped recess A, the two opposite edges of said recess having undercut surfaces A A The edges of the recess A and the undercut surfaces A and A form guides for the movement of a hinge slide B. Pivoted or hinged to this slide is the rectangular shaped plate C constituting the signet portion of the ring which, in its normal position, occupies the recess A. The upper surface 13 of the plate 0 represents one design, and the opposite or undersurface 13 represents another design. To change the design, the plate B is tilted up into the position shown in Figs. 2 and 3, when it is slid along to the position in dotted lines, Fig. 2, and pressed down.

Referring to Figs. 4 to 6 inclusive, a central slot E cut transversely in the signet portion of the ring takes the place of the recess and undercut surfaces already referred to. Working in the said slot E is a hinge slide F provided with a projection stud or head G which kee s the slide from dropping out of the slot. ivoted or hinged to said slide F is the elliptically shaped plate H which constitutes the signet member of the ring. The two flat surfaces II and II'-, of the plate have each a different design. or emblem engraved or otherwise delineated thereupon. The method of presenting the design impressed on the one face of the signet, and reversing it in order to show the other design, is similar to that already described with reference to Figs. 1 to 3. A small pin or projection I is mounted on the center of the ring and the function of the pin is to coact and enga e with a small hole J formed in the plate Ifin either of the two normal positions thereof and this insures stability and the requisite retention of the parts.

It is to be understood that my improvements are also applicable v to scarf-pins, scarf-rings, and pendants."

Claims:

1. A signet ring formed with a recess upon the signet portion of said ring, undercut surfaces constructed at opposite points of such recess in order to constitute guides or guide surfaces, a hinge slide adapted to move in such guides or surfaces, a plate pivoted or hinged tosaid hinge slide in order to move with said slide When tilted up and capable of being pressed down into a reverse or inverted position in order to present one or the other of two signet devices or emblems represented on the two sides of a signet plate, substantially in the manner and for the purposes hereinbefore described and shown on the drawings.

2. A Signet ring formed with a central slot in order to constitute guides or guide surfaces, a hinge-slide adapted to move in such guides or surfaces, a plate pivoted 0r hinged to said slide in order to move with said slide when tilted up and capable of being pressed down into areverse or inverted position in order to present one or the other of two signet devices or emblems represented on the two sides of a signet plate and the means of locking same, substantially in the manner and for the purposes hereinbefore described and shown on the drawings.

In witness whereof I aflix my signature in presence of two witnesses.
